Lactuca sativa, belonging to the Asteraceae family, is a leafy vegetable known for its medicinal properties. This study aimed to understand the mechanism of Lactuca sativa extract with respect to pharmacological action.We investigated the anxiolytic effects of hydro-alcoholic extract of leaves of Lactuca sativa on mice. The behavioral tests performed on mice models to assess anti-anxiety properties were: open field test (OFT), elevated plus maze test (EPM), elevated T maze test, and marble burying test. Increased locomotor activity and time spent in the "open-arm" were observed in extract fed group. Malondialdehyde (MDA) and nitrite levels were decreased, catalase and glutathione levels were increased in Lactuca sativa treated mice. The data obtained in the present study suggests that the extract of Lactuca sativa can afford significant protection against anxiolytic activity.
莴苣属于菊科,是一种以其药用特性而闻名的叶菜类蔬菜。本研究旨在了解莴苣提取物的药理作用机制。我们研究了莴苣叶水醇提取物对小鼠的抗焦虑作用。在小鼠模型上进行的评估抗焦虑特性的行为测试有:旷场试验(OFT)、高架十字迷宫试验(EPM)、高架T迷宫试验和埋大理石试验。在喂食提取物的组中观察到运动活动增加和在“开放臂”中花费的时间增加。莴苣处理的小鼠中丙二醛(MDA)和亚硝酸盐水平降低,过氧化氢酶和谷胱甘肽水平升高。本研究获得的数据表明,莴苣提取物可以提供显著的抗焦虑活性保护作用。
